摘　　要：针对木瓜矿10-1022工作面煤层结构复杂,巷道支护易变性的问题,结合矿井地质条件、地质构造以及赋存状态,分析了煤层顶底板岩性特征,利用自然平衡拱理论对锚杆支护参数进行计算,10-1022工作面运输巷确定采用"锚网梁+锚索"联合支护形式,经校验巷道顶锚杆、巷帮锚杆、顶锚索、帮锚梁以及金属网等参数均能够满足设计要求,能够保证巷道整体稳定性。In view of the complex coal seam structure of 10-1022 working face in Mugua Mine and the variability of roadway support,combined with the geological conditions,geological structure and occurrence state of the mine,the lithologic characteristics of the coal seam roof and floor were analyzed,and the anchor of the natural balance arch theory was used.The pole support parameters were calculated.The support of 10-1022 working face transportation lane was determined by the combination of "anchor beam and anchor cable".The roof anchor bolt,the roof bolt,the top anchor cable and the anchor beam were verified.The parameters such as the metal mesh could meet the design requirements and ensure the overall stability of the roadway.
